The ratio of present ages of Rambha and Sarvesh is 8:5. After 7 years the ratio of their ages will be 5:4. What is Rambha's present age?
Let Rambha's present age = $$8x$$ years and Sarvesh's present age = $$5x$$ years
According to ques, => $$\frac{8x + 7}{5x + 7} = \frac{5}{4}$$
=> $$32x + 28 = 25x + 35$$
=> $$32x - 25x = 35 - 28$$
=> $$7x = 7$$
=> $$x = \frac{7}{7} = 1$$
$$\therefore$$ Rambha's age = $$8 \times 1 = 8$$ years
